Ester Dean

You may recognize her as the voice behind the 2009 smash "Drop It Low," which featured R&B star Chris Brown, but what most don't know is that Ester Dean is the writing mastermind behind some of the biggest pop songs of today. She's responsible for a string of hits for superstar Rihanna, including "Rude Boy," and "What's My Name," and she even penned Nicki Minaj's "Superbass." The Oklahoma native has also worked with artists like Ciara, Christina Aguilera and Mary J. Blige. But with her heart set on a solo career, the self-proclaimed reincarnate of Missy Elliott has plans of taking over the music industry, starting this year. Dean announced on Instagram in 2014 that she had parted ways with Interscope and is now an independent artist.
